徐州INA轴承研制成功了“密封清洁”型轴承。轴承在原标准轴承的两侧有一个特殊的橡胶密封圈。它主要用于防止污垢***轴承，但它不同于维护润滑脂的主要目的——通用机床主轴的主轴承密封圈。
Xuzhou INA bearing has successfully developed a "sealed and clean" bearing. The bearing has a special rubber sealing ring on both sides of the original standard bearing. It is mainly used to prevent dirt from intruding into bearings, but it is different from the main purpose of maintaining grease - the main bearing seal ring of universal machine tool spindle.
1。通过表面感受轴承质量
1. Feeling Bearing Quality through Surface
在销售瑞典轴承的过程中，我发现很多客户都说，只要轴承表面光亮，质量就好，这是不对的。机床主轴支承面亮度应为一种黑色亮度。产生这种黑光的原因是轴承钢是否符合标准，其磨削工艺和切削液的使用，徐州INA轴承前两种是主要的。
In the process of selling Swedish bearings, I found that many customers said that as long as the bearing surface is bright, the quality is good, which is wrong. The brightness of support surface of machine tool spindle should be a kind of black brightness. The reason for this kind of black light is whether bearing steel meets the standard, its grinding technology and the use of cutting fluid. The first two kinds of Xuzhou INA bearing are the main ones.
2。倒角是否光亮
2. Whether the chamfer is bright or not
机床主轴轴承的倒棱不决定不锈钢（不锈钢耐酸钢）轴承的质量，而是反映轴承的加工方法。轴承具有额定负荷高、噪音低、大大降低维护成本、延长机器运行时间等优点。当识别轴承的真实性时，通过触摸徐州INA轴承上的钢印来识别轴承的真实性是更快、更准确的。这种***如果用手触摸就没有接触，但用指甲轻轻地触摸***就可以感觉到。倒角为黑色，说明轴承经淬火等热处理后硬度有所提高。有人认为去除角质黑色不好看，加工不彻底。这是一个误会。
The chamfering of machine tool spindle bearings does not determine the quality of stainless steel (stainless steel acid-resistant steel) bearings, but reflects the processing method of bearings. Bearing has the advantages of high rated load, low noise, greatly reducing maintenance costs and prolonging machine operation time. When identifying the authenticity of bearings, it is faster and more accurate to identify the authenticity of bearings by touching the steel stamp on Xuzhou INA bearings. This kind of stamp has no contact if touched by hand, but it can be felt by touching the stamp gently with nails. The chamfer is black, which indicates that the hardness of the bearing has been improved after quenching and other heat treatment. Some people think that the removal of keratin black is not good-looking, processing is not thorough. This is a misunderstanding.
3。整个网箱比双网箱好。虽然新技术采用单笼，但只节省材料，但其旋转性能不如双笼好。在大多数情况下，轴承疲劳损伤会导致轴承疲劳损伤。一般来说，徐州INA轴承疲劳损伤造成的损伤只有三分之一来自润滑失效的发生，其余三分之一来自污染物错误进入轴承或安装和处理不当。然而，这些类型的损坏都是与工业轴承无关的精细零件，所以在使用高性能轴承时要小心，即使使用不当，也不能达到预期的性能效果，而且容易造成轴承损坏。
3. The whole net cage is better than the double net cage. Although the new technology uses single cage, it only s***es material, but its rotational performance is not as good as double cage. In most cases, bearing fatigue damage will lead to bearing fatigue damage. Generally speaking, only one third of the damage caused by fatigue damage of Xuzhou INA bearings comes from the occurrence of lubrication failure, and the remaining one third comes from the incorrect entry of pollutants into bearings or improper installation and treatment. However, these types of damage are all fine parts unrelated to industrial bearings, so when using high-performance bearings, care should be taken, even if used improperly, can not achieve the desired performance results, and easy to cause bearing damage.
一般来说，机床主轴徐州INA轴承的使用寿命与三个因素有关，一是轴承本身的质量，二是使用环境，三是安装方法。
Generally speaking, the service life of Xuzhou INA bearing of machine tool spindle is related to three factors, one is the quality of bearing itself, the other is the use environment, and the third is the installation method.
